We divide 42879181 by 398
We want to divide 42879181 by 398.

Step 1:
398 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 398

Let's proceed to step 2:
The number 398 fits into 42 0 times, leaving a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 42, we get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 398

Advancing to step 3:
398 goes into 428 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 398 away from 428, we end up with 30.
Grab the next digit (7) from the dividend, add it to 30, then carry on: 307 / 398

Step 4:
398 can be fit into 307 0 times, resulting in a remainder of 307.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 307 to get 307.
Take the next digit (9) from the dividend and append it to 307, then repeat: 3079 / 398

Let's proceed to step 5:
The number 398 fits into 3079 7 times, leaving a remainder of 293.
Use 7 as the next digit of our solution. 
Result so far: 107.0
Subtract 2786 from 3079 to get 293.
Include the next digit (1) from the dividend after 293, then repeat: 2931 / 398

Going ahead to step 6:
2931 divided by 398 is 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 1077.0
Deduct 2786 from 2931 and we're left with 145.
Include the next digit (8) from the dividend after 145, then repeat: 1458 / 398

On to step 7:
When dividing 1458 by 398, we get 3 with a remainder of 264.
The next digit of our result is 3. 
Result so far: 10773.0
The remainder is 264 after subtracting 1194 from 1458.
Take the next digit (1) from the dividend and append it to 264, then repeat: 2641 / 398

Let's proceed to step 8:
If we divide 2641 by 398, we get 6 and a remainder of 253.
Record the quotient 6 as the next digit in the result. 
Result so far: 107736.0
Subtracting 2388 from 2641 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Going ahead to step 9:
The number 398 fits into 2530 6 times, leaving a remainder of 142.
The number 6 becomes the next digit in our result. 
Result so far: 107736.6
The remainder is 142 after subtracting 2388 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1420, and continue the process.

Step 10:
If we divide 1420 by 398, we get 3 and a remainder of 226.
The number 3 becomes the next digit in our result. 
Result so far: 107736.63
If we take 1194 away from 1420, we end up with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Moving on to step 11:
When dividing 2260 by 398, we get 5 with a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 107736.635
If we take 1990 away from 2260, we end up with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 12:
398 can be fit into 2700 6 times, resulting in a remainder of 312.
Put 6 as the next digit of the answer. 
Result so far: 107736.6356
If we take 2388 away from 2700, we end up with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Step 13:
398 can be fit into 3120 7 times, resulting in a remainder of 334.
Put 7 as the next digit of the answer. 
Result so far: 107736.63567
The remainder is 334 after subtracting 2786 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Advancing to step 14:
When dividing 3340 by 398, we get 8 with a remainder of 156.
Record the quotient 8 as the next digit in the result. 
Result so far: 107736.635678
The remainder is 156 after subtracting 3184 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1560, and continue the process.

Moving on to step 15:
When dividing 1560 by 398, we get 3 with a remainder of 366.
Write down 3 as next digit of the result. 
Result so far: 107736.6356783
Subtract 1194 from 1560 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

On to step 16:
3660 divided by 398 is 9 with a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 107736.63567839
Subtract 3582 from 3660 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

After the division, we end up with 107736.63567839 and a remainder of 7.8e-08.
